从php中的json回调中获取POST数据

I am using an API that sends a callback using json POST requests to a page that I set.

Example of the callback:

{
"order": {
"id": "5RTQNACF",
"created_at": "2012-12-09T21:23:41-08:00",
"status": "completed",
"total_btc": {
  "cents": 100000000,
  "currency_iso": "BTC"
},

"custom": "order1234",
}

I need to know how I can take each of these parameters and have them set as php variables.

    Use json_decode to take this string and get an array:

    $array = json_decode($jsonString, true);
    

    If you really want these as individual php variables, use extract:

    extract($array); // now you have a local $order variable
    echo $order['custom']; // etc...
    
    extract($order); // now you have local variables $id, $status, etc
    echo $id;
    

    Example: http://3v4l.org/dqBjT

    Keep in mind that extract could potentially overwrite other local variables, it's not generally considered good practice. I would recommend accessing the data you need in the $array.

    Update: It sounds like you're struggling to access the posting JSON string in the first place. There are two possibilities:

    1. If the data is being sent as a normal POST key/value pair, you can do print_r($_POST) on your page, and you should see where the json string is at.

    2. It's possible that it is being sent as raw POST data and not key/value pairs. In which case you need to look at file_get_contents("php://input");. Try echoing that out. If you find your JSON string, then just set $jsonString = file_get_contents("php://input"); and proceed with the json_decode next.
